Wolf Trap has had some double-take inducing programming over the past couple summers. Sprinkled among the usual suspects -- Garrison Keillor, Mary Chapin Carpenter, the Gipsy Kings -- there's been Ke$ha, Cat Power opening for Billy Idol, OneRepublic and Carly Rae Jepsen.

The trend appears to be continuing this year with news that Robyn and Röyksopp will be playing at the BYOB outdoor venue August 21 as part of their Do It Again tour. In recent years, both acts have taken the stage at the 9:30 Club, and Robyn has opened for Coldplay at the Verizon Center and Katy Perry at Merriweather Post Pavilion. So it will be interesting to see what happens when the Scandinavian super-lineup lands at the usually sedate venue. Intrigued? The presale for tickets begins April 30 at 10 a.m.

And just to perk up your Monday afternoon, here is Robyn and Röyksopp doing "The Girl and the Robot."
